Off the baryonic Tully-Fisher relation: a population of baryon-dominated ultra-diffuse galaxies
Pavel E. Mancera Piña, Filippo Fraternali, Elizabeth A. K. Adams +17
We study the gas kinematics traced by the 21-cm emission of a sample of six HIrich low surface brightness galaxies classified as ultra-diffuse galaxies (UDGs). Using the 3D kine…
Galaxy disc scaling relations: A tight linear galaxy -- halo connection challenges abundance matching
Lorenzo Posti, Antonino Marasco, Filippo Fraternali +1
In CDM cosmology, to first order, galaxies form out of the cooling of baryons within the virial radius of their dark matter halo. The fractions of mass and angular momentum reta…
Tip of the red giant branch distance to the nearby dwarf galaxy [TT2009] 25 in the NGC 891 group
Oliver Müller, Rodrigo Ibata, Marina Rejkuba +1
Dwarf galaxies are key objects for small-scale cosmological tests like the abundance problems or the planes-of-satellites problem. It is therefore a crucial task to get accurate in…
Action-based models for dwarf spheroidal galaxies and globular clusters
Raffaele Pascale, James Binney, Carlo Nipoti +1
A new family of self-consistent DF-based models of stellar systems is explored. The stellar component of the models is described by a distribution function (DF) depending on the ac…
The dichotomy of dark matter fraction and total mass density slope of galaxies over five dex in mass
C. Tortora, L. Posti, L. V. E. Koopmans +1
We analyse the mass density distribution in the centres of galaxies across five orders of magnitude in mass range. Using high-quality spiral galaxy rotation curves and infrared pho…
The tilt of the velocity ellipsoid in the Milky Way with Gaia DR2
Jorrit H. J. Hagen, Amina Helmi, P. Tim de Zeeuw +1
The velocity distribution of stars is a sensitive probe of the gravitational potential of the Galaxy, and hence of its dark matter distribution. In particular, the shape of the dar…
